| 제목 | Innovative reductive remediation of carbon tetrafluoride at room temperature by using electrogenerated Co1+ |
| 초록 | Semiconducting industries are emitted CF4 in huge amount to the environment that should be reduced for healthy environment. Among few ways to remove CF4, electrochemical way of its removal become simple and futuristic technology. Reductive removal of CF4 is more favored due to polymerization during oxidative removal. In the present focus, low valent reductive mediator was selected and utilized to CF4 removal application. At a first step, electrochemical reduction of [Co(II)(CN)5]3-, [Ni(II)(CN)4]2-, [Cu(II)(OH)4]2-, and [Co(II)(OH)4]2- were studied and optimized The CF4 removal was performed out under optimized conditions using electro-scrubbing with online FTIR gas analyzer. The different mediator precursors, [Co(II)(CN)5]3-, [Ni(II)(CN)4]2-, [Cu(II)(OH)4]2-, and [Co(II)(OH)4]2-, were used and the electroscrubbing results showed that the electrogenerated Co1+ or [Co(II)(OH)4]2- precursor effectively degraded up to 99.25% of the CF4 gas. The variations in [Co(II)(OH)4]2- reduction efficiency and cyclic voltammetry revealed CF4 degradation followed by electrogenerated Co1+ mediated. Key words: Homogeneous mediator, Co(I), MER, degradation, Gaseous CF4. |
